This inventiolii relates to a. combined safety razor and sharpeningdevice.

Among the ob 'ects of this invention are the provision of mechanism forfacilitating ,,a rotation of a safety razor blade for moving the facesof the edges on the same side of the blade, respectively, intocooperative engagement with a guard and a sharpening device, and theprovision of means for facilitating a rotation of the razor blade forpresenting either face of either edge to the sharpening device.

Various further and also various more specificobjects, features andadvantages will more clearly appear from the detailed description givenbelow taken in connection with the accompanying drawings, which form a.part of this specification.

The invention consists in such novel features, arrangements andcombinations of parts, as may be shown, described and claimed-inconnection with the-embodiments of the invention herein disclosed by wayof example only. I

"head portion of amodified form of razor embodythe invention;

Fig. 8 shows'a second modification;

Fig. 9 shows parts of another modification in section; and

Fig. 10 shows a partial top plan view of the modification shown in Fig.9.

The combined safety razor and sharpening device includes a handle 10removably secured to a member .11 on which a supporting member 12 isformed or to which it is rigidly connected. The member 12 has suitwithraised portions 14 for spacing the razor blade 15 from the guard proper.Formed on or secured to the opposite side of the member 12 are ears 16in which the-ends of the shaft of a sharpening roller 17 are j ournaled.ThlS roller may be made of any suitable material and may be providedwith a spiral rib as shown. The roller may be rotated by rollmg the sameover the hand of the user or otherwise as desired.

As shown in Fig. 5, the razor blade 15 may be removably secured to aninner clamping or supporting member 23, by an upper clampmg member 21which has bayonet slot connections with the heads of studs 22 extendlngthrough openings in the razor blade. 15 and supported by a lowerclamping member 23. In the modification as shown in Fig. 9, the lowerclamping member 23a may be pro- Vided with aliningstuds 22a cooperatingwith alining holes in the upper clamping plate 21a which may be providedwith a rectangular hole 39 to receive the rectangular head 40 of a studswiveled in the lower clampmg plate 23a. As the head 40 is turned intothe position shown in Figs. 9 and 10, it engages with cam faces at thewalls of the hole 39 to move the clamping plate 21a toward plunger 27-.1 7 In Fig. 1 the razor blade is shownin the operative position with oneedge resting on the spacers 14 on the guard 13 and with the other edgeresting on the sharpening roller 17. The support g member 26 is normallyaligned with the member 12 by means of Fig. 8,

aligning pins 30 on the member 12 engaging in holes 31 in the member 26.These-aligning pins function to hold the edges of the razor blade in theproper operative position.

When it is desired to turn the razor about an axis extending through theplunger 27 the razor is moved into the dotted line position,.shown inFig. 4, by applying pressure to the member 29, and then the razor bladeholder may be rotated by rotating the member 29 or by moving fingerwheels 32 which are nonrotatably secured upon the bearing studs 24,about said axis.

The razor blade may also be turned to present the opposite faces of theedges to the guard and roller by vmoving the plunger 27 and razor bladeinto the position shown 111' lines, Fig. 4:, and then by rotating theclam ing means and razor blade about a longitu 1- nal axis bymanipulation of the finger wheels 32.

If it is desired to sharpen both faces of both edges of the blade, therazor blade may be moved into the dotted line position shown in Fig. 4and may be rotated by means of the finger piece 29 or the finger wheels32 about an axis extending through the plunger 27. By this means thecorresponding faces of hot edges may be sharpened on the sharpenindevice 17. The other pair of correspon ing faces may be brought intocooperative position with respect to the guard and sharpenin roller byrotating the clamping devices and blade by means of the finger wheels 32about an axis extending longitudinally of the blade after the blade hasbeen moved into the position shown by full lines in Fig. 4. Uponreleasing the plunger 27, the faces of the edges of the razor blade willbe drawn into 00- operative position with respect to the guard andsharpenin device whereupon one edges may he s arpened. After this edgehas been sharpened the blade may be moved into the dotted line positionshown in Fig. 4 and rotated about an axis extending through the plun er27 so as to present the other edge to the s arpening device.

Asshown in Fi 7, if it is desired the razor blade may ta e the positionindicated in this figure by making the ears 16a and the part 35 of themember 12a of len hs to accomplish this, or the same may accomplished bythe use of rollers of different diameters. In this way the blade may bemounted at the angle desired for shaving.

If desired, the bearing slots in the ears 166, may be elongated in thedirection shown so that the sharpening roller may travel toward the Theroller 17 may be normally held against the edge of the blade by means ofa 36 which may bear against a roller or the s aft sup orting the roller17 This construction permits the roller to come into uniform yieldingcontact with the blade of the face of the edge of the blade.

for facilitating proper sharpening action throu bout the length of theblade.

In igure 6 the blade holder and blade are shown at an angular positionwith the supporting member 26 resting upon the roller 17, or upon thisroller and the guard 13, in such position that the arts may be cleanedor washed after use, t at is, to place the blade and holderin thisposition it is merely necessa to press upwardl on the finger piece 29 anturn the same t rough a small angle. Thereby the blade holder will beheld in this extended position as long as desired for cleanin or forready replacement of the blade.
